j IMPROVEMENT!GRAIN-CLEANERS AND FERTlLIZ ER-SlFTERS.

Be: it known that I, Jmns A. GREEN, of -Mill Dalegwarrenvcounty, State of Virginia, have invented uew and-useful Improvements in Grain-Clean era and Fertilizer-Sifters combined; and I do hereby declare the followingto he an exact descriptiouthere- I of, reference beinghadute the'accompanying drawing I andIto the le I ing a part of thislspecification, in which :1

tters of reference marked thereon mak- Figure lrepresents a side sectional elevation of the machine; I I I Figure2, a rear view of the machine.

The 'uatureof my invention consists in the arrangement and combination oftheregulating-wheel in front and adjusting wheellin the )rear 'asattached to the screen or sifting-shoe, with themovable hopper in the rear,,whe-n constructed asIherein described.

.Ilhe'object of my invention is'tov clean grain, and,

ffafterward siftgyp'sum, lime, orjashes,as fertilizers, in j the same operatingnnachine, by adjusting the shoe and removing therear hopper. I-

l To enable others skilled in the art to make and use p my invention, 1 will proceed :to describe it, aslfollows A ii'epresentsthe square frame of the machine that I supportsthe,operatingdevices.

B represents the angular hopper at thetop of the p p machine with itsapeifture 0, through which the grain or fertilizer isqpassed down and upon the screen D below. I I

Eisthe incline hoard orgbottom' ofthe shoe that carries the screenings of the grain or the sifted fertil- I 'izer tortheii'ont end of themachine, where they are Qdischargedina heapupoirthe floor. I QGIG' are thevihrating arrns that support the shoe, and are attached at; theixwtops by pivots to. the sides of the frame A, andftheir lower ends fastened by I screws on pivots -to the; bottom or incline hoard E of theshoe. n I

I To the fi-ontYofFtheIshoe is attaeheda pitman, H,

. The sneaulereremaso in these Letters Patent and making m of the same;

that operates on a wrist or adjustable pin, J, that'fits into apertures K of an eccentric-wheel, L, by which the shaking or vibrating movement is lengthened or shortened, as may be required, to give extra motion to the shoe when the fertilizer is being sifted. This regulating-wheel L revolves upon 'the one end of the pinion-shaft M, that is driven by the toothed-wheel N and its crank P.

Across the top and near the rear. of the machine is an adjustable Windlass, R, with two cords, S S, at-

tached to each side of the shoe, the shaft or Windlass having a wheel, T, with apertures on its periphery, into which the hooked catch, U, drops and locks the wheel when the cords are wound up or unwound, for

the purpose ofraising "or lowering the sieve D at its rear end to-the inclination or level required to be operated, and as adjusted for the sifting or cleaning operation. 7 p

At the rear andlower side of the machine is an angular hopper, V, with a curved sheet-iron dasher,

W, against which the grain strikes and is prevented from falling beyo'nd the hopper, while the grain is conducted down the incline sides of the hopper and discharged at the central spout Y.

This hopper is movable, and is only used for the discharge of the grain while being cleaned. It-fits and rests upon two side stripsZZou the inside of the h'ameA of the machine. I

What'Icl-aim as my invention, and desireto secure by, Letters Patent, is

I In the grain-cleaner and fertilizer-sitter hereindescribed, the arrangement of t-heshit'ting shoe with the hopperV and spout V, eccentric L, adjusting-wheel 'l,ani l Windlass R and cords S, when constructed and operating as shown, for the purpose set forth.
